The Facebook OpenGraph Search API is experiencing an outage that began last night somewhere between 7 PM EST and 8 PM EST, as best we can tell. After receiving a tip from a Facebook developer who noticed that his social search engine built on top of the Facebook platform, Booshaka, stopped updating with fresh content, we began investigating. This morning, we performed several searches against the API including queries for popular words like "graduation," and found that although the results displayed show a recent "updated" timestamp, the "created" timestamp is now pushing 15 hours old. Surely, someone on Facebook has mentioned "graduation" in a Facebook update after 7:18 PM EST last night?
